php – google登录oauth2每次重新询问访问权限

我不需要离线访问,因为除了签入用户之外我没有使用任何API调用.无论如何我被困住了,需要一些帮助！

我正在使用谷歌php库(https://code.google.com/p/google-api-php-client/wiki/OAuth2),我甚至将ApprovalPrompt设置为auto.仍然没有运气.

我的代码：

public function googleLogin()
{
    $this->set('connect',"Google login");
    $client = new apiClient();
    $client->setApprovalPrompt('auto');
    $client->setApplicationName("Authentication");
    $client->setClientId(G_OAUTH2_APP_ID);
    $client->setClientSecret(G_OAUTH2_SECRET);
    $client->setRedirectUri(G_REDIRECT_URI);
    $client->setDeveloperKey(G_DEV_KEY);
    $oauth2 = new apiOauth2Service($client);

    if (isset($_GET['code'])) {
        $client->authenticate();
        $_SESSION['token'] = $client->getAccessToken();
        $redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
        header('Location: ' . filter_var($redirect,FILTER_SANITIZE_URL));

    }

    if (isset($_SESSION['token'])) {
        $client->setAccessToken($_SESSION['token']);
    }

    if (isset($_REQUEST['logout'])) {
        unset($_SESSION['token']);
        $client->revokeToken();
    }
    //print_r($client->getAccessToken()); exit;

    if ($client->getAccessToken()) {
        $user = $oauth2->Guserinfo->get();


        // These fields are currently filtered through the PHP sanitize filters.
        // See http://www.php.net/manual/en/filter.filters.sanitize.php
        //$email = filter_var($user['email'],FILTER_SANITIZE_EMAIL);
        //$img = filter_var($user['picture'],FILTER_VALIDATE_URL);

        // The access token may have been updated lazily.
        $_SESSION['token'] = $client->getAccessToken();

        //do stuff with user data
        $data = $this->linkUser($user,"google");
        if ($data['state']=="createUser") {
            $this->set("data",$data);
        }

    } else {
        $authUrl = $client->createAuthUrl();
        header("Location: " . $authUrl);
    }
}

编辑：
我添加了行$client-> setAccessType(“online”);
我不知道这是否是我必须做的唯一工作才能使它工作或者我在浏览器/操作系统之间有错误：
上次我尝试使用lion / chrome它没有用,但是在w7 / firefox上没问题.好吧,或者我只是在放松自己的想法：p
